Dominic Purcell has boarded The CW comic-book drama as a DC Comics villain, reuniting with his Prison Break co-star Wentworth Miller in the 10th episode, The Hollywood Reporter has learned. This marks the first time Purcell and Miller, who played brothers Lincoln Burrows and Michael Scofield, will have appeared together since Prison Break ended in 2009.

Purcell will play Mick Rory, a pyromaniac who finds an outlet for his obsession with fire when he teams up with Leonard Snart/Captain Cold (Miller) and becomes the villain known as Heatwave. Miller was cast in The Flash back in July and makes his debut in episode four. Purcell's character will also be heard from in that same episode.

In DC Comics lore, Heatwave is a member of the Rogues, led by Captain Cold. Heatwave has been featured in animated form on shows such as Justice League Unlimited and Batman: The Brave and the Bold.

Other major Prison Break castmembers have been featured in the Arrow/The Flash universe. Robert Knepper("T-Bag") played The Clock King on Arrow and is set to reprise his role on The Flash, and Peter Stormare (John Abruzzi) is Count Vertigo on the new season of Arrow.

The Flash centers on Central City assistant police forensic investigator Barry Allen (Grant Gustin), who visits Starling City to look into a series of unexplained robberies that may have a connection to a tragedy in his past. Through a freak accident, he is given the power of superspeed, which transforms him into the fastest man alive. Danielle Panabaker, Carlos Valdes, Jesse L. Martin, Candice Patton, Tom Cavanagh, Rick Cosnett and John Wesley Shipp also star.

Purcell is the latest addition to a guest cast that includes Clancy Brown as General Wade Eiling and Tomorrow People'sRobbie Amellas one-half of Firestorm. The first episode features a cameo appearance by Arrow star Stephen Amell, while episode four will feature Emily Bett Rickards' Felicity crossing over to Central City. The eighth episodes of Arrow and The Flash will be a two-hour crossover event.

Purcell is repped by UTA and Untitled. Since Prison Break ended, he has appeared in TV's Common Law, Castle and features Blood Creek, The Killer Elite and Straw Dogs. He'll next be seen in A Fighting Man opposite Famke Janssen and James Caan.
